BMI regardless of body composition is not a credible predictor. Advanced tumor stage and combined treatment modality in head and neck cancer patients which result in synergizing of treatment toxicities, can be used as the reliable risk factors of severe weight loss during radiotherapy.We conducted a retrospective analysis of cancer patients who presented to the hospital with COVID-19 infection at a safety-net hospital in Los Angeles, California, from March 2020 to June 2020. From a list of 1,163 COVID-19+ adult patients, we selected the first 50 patients with malignancy for a preliminary analysis. There were 23 males (46.0%) and 27 females (54.0%); the median age was 60.5 years (IQR 47 - 72). Thirty-nine (78.0%) of the patients were Hispanic. The most prevalent cancers were genitourinary (14, 28.0%), hematologic (11, 22.0%), and gastrointestinal (10, 20.0%). Twenty-one (42.0%) patients had active disease at COVID-19 diagnosis, while 25 (50.0%) had no evidence of disease (NED), and 4 (8.0%) were unknown. Over 1 in 3 admitted patients experienced a "severe outcome," which was defined as critical level care (14, 34.1%), use of vasopressors (9, 22.0%), intubation (8, 19.5%), or death (5, 12.2%). Patients with severe outcomes were found to have statistically higher values of absolute neutrophil count (p = 0.005), aspartate aminotransferase (p = 0.049), high-sensitivity C-reactive protein, (p = 0.001) and lactate dehydrogenase (p = 0.040) on admission. Overall survival (OS) was not statistically different between those with hematologic versus solid malignancy nor between those with active disease versus remission (both p&gt;0.05). Thirteen (81.3%) of the 16 patients who had cancer treatment in 2020 experienced delays in cancer therapy. Additional cases are being evaluated as the pandemic continues with the goal of identifying areas for potential intervention to improve outcomes in this at-risk population.Nearly 1/3 of lung adenocarcinomas have loss of STK11 (LKB1) function. Herein, a bioinformatics approach was used to determine how accurately preclinical model systems reflect the in vivo biology of STK11 loss in human patients. Hierarchical and K-mean clustering, principle component, and gene set enrichment analyses were employed to model gene expression due to STK11 loss in patient cohorts representing nearly 1000 lung adenocarcinoma patients. K-means clustering classified STK11 loss patient tumors into three distinct sub-groups; positive (54%), neuroendocrine (NE) (35%) and negative (11%). The positive and NE groups are both defined by the expression of NKX2-1. In addition to NKX2-1, NE patients express neuroendocrine markers such as ASCL1 and CALCA. In contrast, the negative group does not express NKX2-1 (or neuroendocrine markers) and is characterized by significantly reduced survival relative to the two other groups. Two gene expression signatures were derived to explain both neuroendocrine features and differentiation (NKX2-1 loss) and were validated through two public datasets involving chemical differentiation (DCI) and NKX2-1 reconstitution. Patients results were then compared with established cell lines, transgenic mice, and patient-derived xenograft models of STK11 loss. https://www.selleckchem.com/products/dual-specificity-protein-phosphatase-1-6-Inhibitor-bcl.html Interestingly, all cell line and PDX models cluster and show expression patterns similar with the NKX2-1 negative subset of STK11-loss human tumors. Surprisingly, even mouse models of STK11 loss do not resemble patient tumors based on gene expression patterns. Results suggest pre-clinical models of STK11 loss are pronounced by marked elimination of type II pneumocyte identity, opposite of most in vivo human tumors.The prognosis of patients affected by malignant pleural mesothelioma (MPM) is presently poor and no therapeutic strategies have improved their survival yet. Introduction of miRNA mimics to restore their reduced or absent functionality in cancer cells is considered an important opportunity and a combination of miR's might be even more effective. In the present study, miR-16 and miR-34a were transfected, singularly and in combination, in MPM cell lines H2052 and H28, and their effects on cell proliferation and sensitivity to cisplatin are reported. Interestingly, the overexpression of both miRs, alone or combined, slows down the cell cycle progression, modulates the p53 and HMGB1 expression and increases the sensitivity of cells to cisplatin, producing a marked impairment of cell proliferation and strengthening the apoptotic effect of the drug. However, the co-overexpression of the two miRs results more effective only in the regulation of the cell cycle, but does not enhance the sensitivity of MPM cells to cisplatin. Consequently, although the potential of miR-16 and miR-34a is confirmed, we must conclude that their combination does not improve the response of MPM to chemotherapy.Alopecia is one of the most common and afflicting side effects associated with chemotherapy treatments. Scalp-cooling devices were introduced to reduce hair loss and improve the hair volume recovery in patients undergoing chemotherapy.
This is a single center, prospective observational study conducted from 01 February 2019 to 31 January 2020, in patients undergoing chemotherapy for various cancers. The extent of alopecia was assessed by two independent clinicians by reviewing the photographs taken at baseline, during each session, and 4 weeks from the last scalp cooling session.
A total of 100 patients (female 94 and male 6) were enrolled in the study, with a mean age of 53.5 years. Of 100 patients, 40 received anthracycline based chemotherapy, 45 received taxane based chemotherapy, 9 received both, and 6 received other chemotherapeutic agents. By the end of the study, 31 patients experienced grade 0-1 alopecia and 69 patients had grade 2 alopecia. On multivariate analysis, chemotherapeutic agent was found to be an independent factor for delaying the onset of Grade 2 alopecia (anthracycline vs taxanes (OR 0.71; 95% CI (0.51-0.92);P?0.04)The most common adverse events reported during the scalp cooling sessions were chills (7%), and chills with headaches (6%). Scalp metastasis and scalp cooling discontinuation rates were observed to be very rare. No serious adverse events related to device were observed.
Scalp cooling was observed to be more effective in reducing chemotherapy-induced alopecia in patients treated with taxane-based chemotherapy over anthracyclines. Scalp cooling sessions were well tolerated. Scalp metastasis and scalp cooling discontinuation was observed to be very rare.
